Front

Because of inertia, a resting object will remain at ________.

Back

rest

Front

To find the WEIGHT of an object, multiply its MASS (in kg) by gravity (in m/s²). What is the formula?

Back

Weight (Fg) = Mass (m) x Gravity (g)

Front

What is the weight of a 10 kg mass on Earth?

Back

100 Newton

Front

Why do all of the planets orbit the Sun rather than Earth?

Back

The Sun has more mass.

Front

Which weighs more: a pound of feathers or a 1 pound bowling ball on Earth?

Back

They weigh the same.

Front

What is the approximate weight of a 50 kg object on Jupiter if it weighs 490 N on Earth?

Back

980 N

Front

Define mass in physics.

Back

Mass is the amount of matter in an object, measured in kilograms (kg).

Front

Define weight in physics.

Back

Weight is the force exerted by gravity on an object, measured in Newtons (N).

Front

What is the gravitational acceleration on Earth?

Back

Approximately 9.8 m/s².

Front

What happens to the weight of an object if it is taken to a planet with stronger gravity?

Back

The weight of the object increases.
